Engine died after knocking and shutting off in the middle of tragic. Engine will not even make a sound now. Spoke to the dealership ans they refused to repair my car bc 1) I stopped going to the dealership for maintenance back in 2016 and 2) I have not completed any of the recalls.

My son and his pregnant fiancé were traveling on [XXX] West bound Thursday [XXX]. They just got out of a construction zone near Rolla MO. At mile marker [XXX] the engine shut down with no warning at 60 mph and all the lights on the dash came on. He had a hard time controlling the car due to the steering being very tight and the brakes were manual. They got a tow to a safe place. I drove 5 hours to meet them and used a scanner to see what codes the car had. Zero codes showed up on my scanner. The engine immobilizer was engaged. We could not get the car started so I rented a U-Haul and car dolly and brought the car back to Indiana to the Avon IN Andy Mohr Kia dealer where we bought it. It was scheduled to be seen Tues [XXX] at [XXX]. I did not hear from them, so I called at 2:30. They informed me an engine was ordered for the vehicle. The Knock sensor detected a bearing knock and shut the car down at high speed on an interstate. The car has no outstanding recalls. I asked about the Knock sensor recall for Kia and ask why the car did not go into limp mod so they could make it safely off the interstate. No response from the dealer. This is a terrible design to have the car shut down at high speeds on an interstate. This could be deadly. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My Kia motor was ordered Kia gave me a hard time to rent me a car. I went 2 months with NO Transportation. Finally I got my car back and every 3 weeks different lights are coming on. Seat belt is now own O2 sensors had to be changed Now Cadillac Converter Light is on. I didn't know that getting a new motor I would have to keep spending money that I don't have. Kia should be responsible for this it shouldn't be my fault that I'm being punished for a Bad MOTOR.

The car is available for inspection upon request, but I plan to finally get rid of it soon. I worry greatly about the next driver that ends up with this car. While driving, a message pops up on the dashboard that says "Check Hybrid system. Stop vehicle and turn off engine". I've learned that I have about 15 to 30 seconds to find a safe place to pull over or the car will shut off on it's own. This has happened on the freeway at 70mph and it's happened at 20mph while driving through my neighborhood. I bought the car used in 2017 and this would happen once every six months or so. In the past couple of years it's gotten more frequent. This car is going to get me or someone else seriously injured or killed. I'm always on edge that this will happen while I'm on the freeway in an area without a shoulder. Then I'll just be sitting immobile on the highway, trying to get the car to start back up and I'll get rear-ended by an unobservant driver at 65mph. I've taken the car to a Kia service department twice. The first time they couldn't reproduce the issue and told me to bring it back when it happens again. I took it in for a second time a couple years later and they told me it was the high voltage fuse. They kept my car for a month, gave me the runaround and never replaced the high voltage fuse. After doing some research online, I read that other Optima Hybrid drivers were told to change their high voltage fuse from 125A to 150A. I performed this replacement myself and I still experience the issue. There were no other warnings prior, just the "Check Hybrid system" message before the car shuts off.

Exact same issue happened to my 2014 Kia Optima Hybrid (NHTSA ID Number: 11556409). I was traveling on the freeway approximately 65mph and out of nowhere the engine turned off, brakes did not work and steering quality went to a manual operation. I almost got into a serious accident as I could not control my vehicle. The hybrid system warning light, to stop using the vehicle became illuminated for approximately 30 seconds. The vehicle was towed to the local dealer ( Koons Kia, 14208 Richmond Hwy, Woodbridge, VA 22191, United States). We are still awaiting diagnostics. A few years ago the standard hybrid light came on (not the same warning light) in which we took it to the same dealer to fix. It was still under warranty at the time, however took them weeks to fix the issue as I had to take it back multiple times. They eventually replaced something in the hybrid system that was worth around $5-6k, since then we have had no other issues. We conduct the routine maintenance on the vehicle, passes all inspections.

I was with my family on PA I-476. While traveling home in our 2014 Kia Optima the vehicle-??s dash lights such as oil lamp, battery, etc popped on. As soon as I noticed the lights the vehicle had completely lost all drivability. Lights operable and possibly radio and accessories but I had to react so quickly as it was so unexpected. The vehicle completely lost its function and I was unable to operate it but in the capacity of steering and hardly able to break. Lost all power components. We are so thankful I was able to make a split second decision to dodge traffic while vehicle was decelerating, 18 wheelers going by 70+ mph (speed limit) and pulled off to one of the few shoulders. This scenario was so dangerous that if I didn-??t believe in a higher being before, I do now! Most the lanes are sandwiched by concrete barriers and there happened to be a coned off area I was able to decisively pull over to. There was no warning this was happening. The vehicle was operating normally. The engine compartment was smoking and all I could think was to get my family away from traffic. The look on my wife and daughters face and the words my daughter asked me was life changing. The vehicle is at Kia dealership since Saturday night. It-??s Wednesday and they cannot provide diagnostic yet but are charging me for a starter already? They began to inspect vehicle Monday.

engine was replaced per CASE # 14397135, and PI1803Y/Z, SINCE engine repair Turbocharger Boost Control Position Sensor -??A-?? Circuit High CODES (P2562 & P2565) continuously come and go. Check engine light comes on and off for the same codes. Knocking noise continues, loss of acceleration as if voltage or gas was lost, steering wheel speed control buttons (+/-) no longer properly function since engine replacement. It now has a class 2 leak. Safety risk:when driving it loses speed or fails to accelerate may cause crash. KIA dealership has tried to access the code but Codes are spontaneous, same for loss of acceleration.

Summer 2017 The engine failed while driving with my family. The engine seized and a fire was engulfed. I was in the interstate and we feared for our life. Out of town visiting family we were stranded in another state for a month waiting for repairs. Kia took the vehicle and replaced the engine with another faulty engine that has seized several times while commuting. I have been living in fear and anxiety since this incident. I never know if I start my engine if I will loose my life. Summer 2023 3 teenagers watched a viral tic tok challenge and learned how faulty the cylinder that Kia installed was. The teens then trespassed into my home, broke the windows and stole my vehicle. I have lived in fear since this has happened. I have lost jobs, income, and peace due to The purchase of this vehicle. Kia has never assisted or kept the promises they made to restore the vehicle. These past 10 years agave been a nightmare and as an African American woman I believe I was targeted as a purchaser for this make and model. My life had been hell since the purchase of this vehicle. I have not been able to satisfy payment due to repairs, thefts, fires, and more. Please anyone. Someone. Help. This is the most heartbreaking experience as an American. I have worked for my country 20 years and do not feel like an equal citizen. I have been homeless, jobless, unstable, and watched my life and family life flash before me in near death accidents involving this car. When I purchased this car I had a great job, credit score, and home. Now I have more anxiety, fear, bills, and no help with this Kia.

This will be my Second Review about this dealer's service department. I'm not reviewing the service technicians but I'm reviewing the customer service, porters and advisors. I had my vehicle towed there on the 23rd of August after waiting a full month for my appointment. I have called to check on any updates to see have my 2014 Kia has been looked at. 1st time they didn't even know my vehicle was there even after confirming with a service representative. 2nd time I was told when my vehicle was assigned to an advisor someone would contact me. Today I called and spoke with [XXX] and he put me on hold to speak with an advisor. After 15min Of silence. I thought maybe I was forgotten about by mistake. I called back and [XXX] who stated this was him name when I called back was very RUDE. He stated I put you on hold to someone who would speak to you and hung up on me. This is when I called back to speak directly to a supervisor in the service department. I been on hold over 16min as I write this review. No hold music just silence. My 1st encounter here for a recall I was told to pull in lane and leave keys in car. I waited as porters took other vehicles and mine sat blocking lanes. To my amazement I listened to them saying what assholes people where for leaving their cars, when an advisor took the keys. This is an great establishment with a lot of History to have its name tarnished by bad apples. 22min on hold and one has cared to even speak to me. Please pay attention to hold times at to of screen.
